摘　　要：针对五阳煤矿76.2号区段2号总回风巷在掘进过程中围岩性质不断发生变化,将穿过泥岩、砂质泥岩、细粒石英砂岩等多种岩层的情况,采用数值模拟研究复杂地质条件下软岩穿层巷道非对称变形规律,以及在此基础上提出适应五阳煤矿软岩穿层巷道的围岩稳定性控制技术,充分发挥支护结构的支护性能,在加快巷道掘进速度的前提下,保证巷道能够在服务期内的安全使用。In view of the fact that the surrounding rock properties of No.2 total return airway in No.76.2 section of Wuyang Mine were constantly changing during the excavation process, it would pass through various rock strata such as mudstone,sandy mudstone and fine-grained quartz sandstone. The numerical simulation was used to study the asymmetric deformation law of soft rock crossing roadway under complex geological conditions, and on this basis, the stability control technology of surrounding rock suitable for soft rock crossing roadway in Wuyang Mine was put forward, so as to give full play to the supporting performance of supporting structure and ensure the safe use of roadway during the service period under the premise of accelerating the excavation speed of roadway.
